FRONT-WHEEL BBAKE.

Application filed October 12, 1921. Serial No. 507,322.

To all whom it may concern:

Be it known that I. HENRY J. Now, a,

improvements in front wheel brakes which are more especially adapted for use in connection with motor vehicles,

The general object of the invention is to provide a device of this kind which is operable simultaneouslywith the operation of the rear wheel brakes and which will operate with equal efiiciency with the front wheels in any position. I

A further object of the invention is to provide an attachment of this kind which is strong and durable and in which suitable provision is made for bracing the steering knuckles-against any unusual strain which may be caused by the application of the brakes ofthe front wheels.

It is also an object of the invention to provide suitable means by which the brake is particularly adapted for attachment to any of the various standard types of automobiles.

My invention will be described in connection with the accompanying drawings, in which Figure 1 is a plan view of the front por- -ion of an automobile frame with my invention applied thereto.

Figure 2 is a vertical longitudinal sectional view of the same.

'Fi ure 3 is a detail view showin the de- & s tails of the connection between the brake and front wheel and steering knuckle.

the frame'nf theautomobile having a front axle 2 and front wheels 3 which are pivotally supported on the steeringdmuckles 4 in the usualmanner. In carrying-out my invention I provide a brake drum 5 for each of the front wheels which may be secured. to

the inner side thereof by suitable bolts 6,

the wheel being removed from the hub for" this purpose. A bracket 7 is secured to tln steering knuckle and transversely pivoted therein is a spindle 8 having the usual means at its inner end for applying the brake shoes 9 to the'drum. The spindle is rocked by a lever 10 secured to its outer end for the purpose of applying the brake. In orderto" prevent the twisting or breaking of thesteering knuckle by any sudden strain caused by the application of the brake I provide a forked brace 11, the front ends of which are in threaded connection with the eye bolts 12 journalled on the upper and lower ends of the knuckle. The rear end of the brace has a universal connection 13 with a bracket arm 14 secured to the frame of the automo-g bile.

In order that the-braces may have k the same relation to the knuckles under all conditions the connections 13 shouldbe in alignment with the pivot of the wish-bone or bracing member which braces the front over the sheaves and connected to one end of the lever 10 for actuatingthe same to apply the brakes. A coil spring 33 is preferably provided for holding the lever 10 to take up any possible slack in the cable 19 and to hold the same in engagement with the sheave. The rear end of the cable 19 is connected to a lever 20 which. is secured to or integral with a sleeve 2i carried by the transverse rock shaft 22, It will be understood that a cable and actuating arm and sleeve may be provided for each of the front wheels and the sleeves 21 may be rigidly connected to each other by a transverse bar 23 as shown in Figure 4; One of the sleeves 21 has an upwardly extending arm Qel which is connected by a link 25 to a collar 96 which is longitudinallyadjustable on the usual brake pedal 27 to vary the amplitude of movement of the brake shoes with relation to the throw of the brake pedal. It is of course understood that the brake pedal controls the rear wheel brakes (not' shown) in the usual manner. i

in the application of my device to an au-' tomobile in which longitudinal leaf springs are used for supporting the front end of v in cooperative the frame the pivotal connection 13 may be constructed with a slidable box 31 as shown in Figure 5 to allow for the longitudinal play between the frame and the front axle.

In applying my invention to the front wheels it is necessary to remove the speedometer gear. In order to take the place of this a ring gear 32 may be secured to the outer surface of the brake drum and a pinion may be provided for securing the proper ratio for driving the speedometer.

While I' have shown and described ainumber of ways in which the invention may be applied to automobiles of standard make it will be understood that other changes and adaptations may be devised within the scope of the invention as claimed. 1

'1 claim as my invention 1. In an automobile having rear wheel brakes, a brake drum provided with means for attaching the same to the front wheel of an automobile, a brake shoe, means for attaching the same to the steering knuckle 'ion to said drum, pivoted means for bracing said knuckle from the frame of the automobile, a lever for operating the brake shoe, and means for operatively connecting the lever to the brake pedal, whereby the front wheel brakes are operated simultaneously with the operation of the rear wheel brake.

2. The combination with the frame, brake pedal, front wheels and steering knuckles of an automobile, of a pair of brakes mounted in operative relation to said wheels, braces journaled at their front ends on the steering knuckles and pivotally connected at their rear ends to the frame, and means resales connected with the brake pedal for operating said brakes when the pedal is depressed.

3. The combination with the frame, brake pedal, front .wheels and steering knuckles of an automobile, of a pair of brakes mount ed in operative relation to said wheels,

braces journaled at their frontvendson the steering knuckles and pivotally connected at,

their rear ends to the frameyleversrcarried by the steering knuckles and operable'to'operate the brakes, sheaves supportedby the steering knuckles and braces, and cables.

connected with the levers and carried over said sheaves and connected with the pedal,

said cables and levers being operable when the pedal is depressed to apply the brakes.

4. The combination with a frame, front wheels, steering knuckles and front wheel spindles of an automobile, of front wheel brakes, means for controlling said brakes,

spindles of an automobile, of "front wheelbrakes, means for controlling said brakes,

. and a pair of members having pivotal connection with the frame and each having a pair of forwardly extending arms bracing thecorresponding steering knuckle at points above and below the spindle of-the wheel.
